u 'This invention relates to an improvement in handcus or shackles; andby the term fzvhandcus? as hereinafter used I wish to be understood as'including either devices adapted for use as handcuffs ormade ofsuf-Vicient size to be used as leg-irons, the object of the invention` being`to produce at -a re. duced cost for manufacturev handcuffs constructedwith particular'reference to lightness,-simplicity, fewness of parts,and 'Y seeA ,curity` againstv being picked by the pris'- oner.

Handcuffs or shackles as usually employed are arranged inpairs;` but forthe purpose of illustration only 'one handcuff is shown.

vEach cuff consists of a body or case 2, to

which a chain 3 is swiveled inthe usual way, and to one end of thecasean arm 4 is swiveled, they-outer end of the arm being formed withlocking-notches 5 and adapted to 'pass' through Van opening 6, formed`for it inthe case, the ycase being openaty one side and closed by a cap7 in substantially-the usual manner. In the case near the locking end isa circularrecess or chamber 84, and from this chamber a channel 9extends into the opening 6.` vIn the bottom1o'f the chamber* aretwospring-studs 10 and 1,1, and in the center ofthe chamber is a lpostwhich will yhereinafter be termed the key-post7 12. Lo-

connected with this disk by a ylink 14 is a locking-bolt 15, -the boltbeing arranged in. the channel and having a nose 16 ada :ted to engagethe notches 5 when .the end ofte arm passes through ,thev opening 6, theend ,of the' having a slot 17 to permit yof more or less independentmovement between vthe bolt .and

be entered into the'hole18` in the disk. 'The hub of this tumbler isalso formed .with an angular recess 23 toreceive acorrespondinglyshapedkey to rotate said tumbler.

Mounted inthe case .atone. side of. the chamber 8 vis a spring 24, theupperarm 25 of which extends into the chamber and against the rear endof the bolt 15, soy as to normally force 'that bolt forward. Mounted inthe cap-plate 7 near thekeyhole 26, is a spring push-button 27, whichwill bear upon the upper face of the tumbler yand so that the tum-4 blermay befdepressed. In the locked position, as shown 1n Fig. 2 ofthe-drawings, the

holeflS in the disk stands over thespring-pin 10, by which .the diskaisheld against rotation, and in this position .the bolt 15 isthrownforward, so as to standin `the opening 6 andengage with one ofthenotches 5 of the arm, and hence lock that end of the arm to fthecase. To open the handcuff, .a key is inserted through the hole 26 andinto the angular `recess 23 'in the tumbler andthe tumbler forceddownward thereby against the ypressure of the spring 20 until the pin 22in the under freefto rotate therein is a locking-disk 13, and I nk 14,which is connected with vthelbolt 1.5,.

IDO

faceofthe tumbler. depresses the spring-pin 10, so as to releasethe disk13e. If then the key be turned, Vthe disk will be rotated by theengagement of the tumbler f'therewith -either by the continued pressure,so 4as to hold fthe piny 22 in thehole' 18, or by the en agement of theltumbler with thestud 19.' l hen the disk is rotated to its'unlockedposition, the hole 18 will stand over the spring-pin 1 1' whichisthenforced u ward into ,the hole. 15

and Se @elite heldthe .,iekiirlitsseleekedfpof IlO sition. This movementof the disk will have turned-the link 14, so as to withdraw the nose ofthe bolt 16 out of the opening 6, leaving the arm free to be moved backand forth therein or entirely withdrawn therefrom. lf now itbe desiredto lock the cuff without the use of the key, the spring-button 27 willbe depressed, and this inward movement of the button forces the tumblerdownward, so that the pin 22 carried thereby will depress thespring-stud l1, thus releasing the disk 13, at which time the spring 24will act to force the bolt forward, so that the nose 16 thereof is inposition to engage with the notches 5 of the arm, but the bolt is freeto move rearward. This permits the arm to be passedgagement with thespring-stud 10, in which position the bolt 15 is held against movementin either direction, and thereby securely locks the arm in the case-inother words, doubly locks it in a closed position. It will thus be seenthat while the cuH cannot be unlocked without a key after being openedby the key the keyV may be removed, yet when placed upon a person can beimmediately placed in condition for operation by a mere pressure uponthe spring-button 27.

Instead of providing the spring-button 27 to be moved inward against theface of the tumbler a slide 28 may be arranged upon the inner face ofthe cap 7, as shown in Fig. 6, this slide having a beveled nose 29,adapted to enter between the top of the tumbler and the inner face ofthe cap, so as to force the tumbler downward when the slide is movedagainst it, the slide being connected with a thumb-piece 30 on theoutside of the cap for operation in the same way as was the springbutton27, except that it is moved longitudinally instead of bein pressedinward.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The herein-described improvement in handcuffs comprising a case, anarm pivoted thereto and adapted to pass through an opening in said case,said case formed with a chamber having a spring-pin mounted therein, achannel extending from said chamber to the opening for the arm, a boltlocated in said channel to engage said arm, a disk mounted in saidchamber and connected with said bolt, said disk formed with a holeadapted to engage Vwith said spring-pin, and a tumbler adapted to engagewith said disk whereby the said disk may be rotated, substantially asdescribed.
